hlhi=REFlLLABLE RECEPTAQLE.

SPEGIFIJATEON forming part of Letters Patent No. 745,988, dated December 8, 1903. Application filed December Z1, 1901. Serial No. 86,727. (No model.)

To all LU/b07771 if; may concern:

Be it known that l, HENRY V7. AVERY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Non-Refillable Receptacles, of which the followingis full, clear, and exact description, reference being had to the accompanying drawings.

My invention relates to means for preventing the refilling of bottles, jugs, &c., after they have once beeueinptied. ltcomprehends a valve mechanism so operating and held in the neck of the receptacle oy some suitable baiiie. Such battles are illustrated in my prior patentsfhlo. o'70,266,grantedto nie March 19, 1901, and No. 6885M, granted to me December 10, 1901.

Assuming that a suitable baffle is applied to the neck, preventing the removal of the valve structure or interference with its action the present invention provides this valve structure in a form which shall be very simple, while being efiicient to prevent refilling in all positions of the bottle. The valve structure comprises two balls, a lower light ball and an upper relatively heavy loall, contained within a chamber formed in the neck, which so shaped that when the bottle or receptacle is on its side or out of the vertical posiiion the heavier hall rolling down an incline will, by gravity, force the lighter ball ahead of it Ioward its seat, where any incoming liquid will snugly seat it. Thus if the bottle is inverted it cannot he E'Ql'lllizkl,f0l' the light hall will float against its seat and prevent entrance, while if the bottle stands upright the heavy hall resling on the light ball will hold it down to its seat, and if the bottle is held. sidewise the same aciion will follow by the heavy hall rolling down the incline of the neck.

it has heretofore been atteinped to use the light and heavy hall with a plug in the heck of the vessel, providing an incline for the heavy ball; hut so far as I am aware these halls have not been confined within a surrounding nech so formed as to itself present the incline by which the heavy hall insures the sealing of the light hall.

lily construction is of advantage, as it requires no extra parts whatever besides the two balls and is independent of the form of baffle employed. It allows the use of the simplest form of baffle, as shown herein.

The chambered neck operating as above described is an essential element of the combination constituting the present invention, as hereinafter more fully explained, and definitely set out in the claim.

The drawings clearly illustrate my invention, wherein Figure 1 is a vertical central section of a non-refillable bottle embodying the invention and provided with a battle of substantially the form set out in my Patent No. 688,57 L. Fig. 2 is a view of the same, the bottle neing on its side. Fig. 3 is a plan of the baffle.

The bottle orother receptacleis designated A. It has a neck portion with a curved chamber a, as shown. Above this is an enlargement at, and above this is the corlz portion (0 B represents the light hall and C the heavy ball. These occupy the chamber a, as shown, being prevented from leaving the same by the baffle D, which, as shown, is a thin plate adapted to be bent on its diameterand d ropped through the neck portion a and then flattened by pressure into the form shown in Figs. 1 and Thereafter a cork Eis placed in the neck portion. Now the valve 15 and C does not prevent the exit of the liquid, which when the bottle is tipped up passes out under the light hall B and over the heavy ball 0, as shown by dotted lines in Fig. 2, whence the liquid escapes through the sealloped openings d of the baffle. attempted to refill the bottle,however, it will be seen that in anything approximating an upright position the heavy ball will rest on the light and hold it to its seat. It the bottle be completely inverted, the light hall B would float on the liquid and prevent the entrance. \Vhen the bottle is on its side, either horizontally or near enough thereto so that the liquid might pass into the interior and the air escape therefrom, the hall 0 rolling down the incline of the chamber forces the ball B ahead of it toward its seat. This action is aided by the force of the incoming liquid which will snugly seat the light ball. Thus in every position of the receptacle admission is prevented.

By making the chamber a an integral poriCO tion of the neck I simplify and cheapen the construction, enabling the bottle to be blown in an ordinary mold and doing away with any cemented plugs or other arrangements which are expensive and liable to contaminate the contents. As is well known, bottles blown in the same mold vary considerably in thickness, and consequently any tight-fitting plugs or cemented devices have to be especially formed for each bottle or the bottle ground for the plug, which in either case causes a considerable expense. Moreover, there is always danger of the cement working loose or dissolving in the contents of the bottle. By my method the chamber is simply blown and does not have to be accurate. There is no subsequent finishing or grinding and no cement, as there is not nicety of fit required at any point. Finally, I am enabled to use a bathe designed solely with reference to its capabilities as a baffle without its being hampered by having to form a portion of the valve structure.

The light ball B may be made of cork, the heavy ball G of glass, and the baffle D of metal, though other materials may be employed, if desired. The upper end of the chamber is somewhat larger than the lower end to allow convenient access of the two balls from above. I also find it convenient to make the heavier ball the larger of the two. The baffle D may be marked with a trade-mark or other proprietary data to prevent any substitution for it if it should be removed.

It will be observed that the interior of the chamber a. is curved inwardly at the upper portion thereof to form a shoulder a and that the depth of the chamber from the shoulder to the valve-seat is substantially equal to the combined diameters of the balls B and C. By this construction the weighting-ball O opcrates readily when the bottle is in a horizontal position to seat the valve-ball B.

I claim Anon-refillable bottle havinganeck formed integral therewith and comprisinga chamber provided with a valve-seat at the lower portion thereof, said chamber having a continuous concave interior surface extending inwardly at the upper portion thereof to form a shoulder, an enlargement above said shoulder, a retaining-baffle in said enlargement, a stopper-receiving portion above said enlargement, and alight valve-plug and a weightingball in said chamber, substantially as described.

In testimony whereof I hereunto affiX my signature in the presence of two witnesses.
